BOX-COVERlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 504,551, datedSeptember 5, 1898.

Application filed May 31, 1892. Serial No. 435,017. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BRAND- STAEDTER, a citizen of the UnitedStates, residing at Hanover, in the county of York and State ofPennsylvania, have invented certain new and useful Improvements inBox-Covering Machines; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, and totheletters of reference marked thereon.

The present invention has relation to that class of machines forcovering the exterior of boxes with paper, cloth, or other likematerial, in which the covering is fed through the machine in strips andcoated with paste from a paste-supplying device, then applied to the boxand the strips afterward severed by a knife or other severing device.

It is the object of the invention to improve the construction of thisclass of machines, whereby the work of covering the box will beaccomplished quickly and effectively, and consists in a machineconstructed substantially as shown in the drawings and hereinafterdescribed and claimed.

The invention is clearly illustrated in the accompanying drawings,which, with the let ters of reference marked thereon, form a part ofthis specification, and in which Figure 1 is a longitudinal verticalsection through the machine on the line Y Y of Fig. 2, looking in thedirection of the arrows. Fig. 2 is a plan with a portion broken away.Fig. 3 is a detail of the cross showing its manner of adjustment. Fig. lis an end elevation of the strip-severing mechanism. Fig. 5 is aperspective view of the paste tank and jacket, removed.

Likeletters of reference indicate like parts throughout the severalviews in which they appear.

Referring now to the details of the drawings by letter, A designates asuitable support or table designed to support the operating parts. Thetop A of the table has near one end an opening 0. over which is arrangedthe paste tank, and beneath or in which opening is arranged the heater Awhich in this instance is shown as a gasoline burner of which a is thesupply receptacle, and a the supply pipe from the said receptacle. Thispipe is held in a suitable bearing a on the frame or table and is thereheld by a set screw or analogous means a as seen by dotted lines in Fig.2, so that the burner may be adjusted with relation to the paste tank asmay be desired. The burner can thus be lighted either under the machine,or, by loosening the set screw, the tank or receptacle can be let downto the body of the machine and then given a half turn which will bringthe burner to the outside of the frame when it can be lighted and thenturned back to its normal position where it will be held by its setscrew engaging the supply pipe as before.

13 is the'paste or adhesive receptacle; it is formed with doubleinclined bottom as seen in Figs. 1 and 5 and with side flanges b as seenin Fig. 5, which are designed to engage the upper edges of the sidewalls of the water tank B as seen in Fig. 1, the receptacle B beingdesigned to set down within the tank B and at its outer end it isprovided with a shield B extending outward and which serves to keep theheat away from the strips of paper or cloth as they are passing over therollers soon to be described. The tank 13 has a surrounding flange bwhich rests upon the top of the table and thus forming a chamber orspace H for the heat, as will be seen from Fig. 1, the receptacle Bbeing of less depth than the tank as shown so as to provide a space bfor water between the heat and the bottom of the paste receptacle asclearly shown in Fig. 1. Any suitable means may be employed for heating.All the heat is utilized by reason of the arrangement of parts abovedescribed. The paste receptacle is of less length than the water tank soas to leave a filling opening B at the end as seen in Fig. 1, which isclosed by a drop-lid B hinged to the end of the water tank andhavingafiange b to fit over the end of the paste receptacle as seen inFig. 1 and close the said opening. This permits of refilling of the tankwhen necessary without taking off the paste receptacle and also thedrop-lid acts as an automatic valve to allow of the automatic escape ofany surplus steam that may be formed. Air can be admitted to the space 6or the heat reduced by means of the draft slide or ventilator 11provided at one end of the flange of the water tank as seen in Figs. 1and 5. The paste receptacle is so arranged relatively to the other partswhich will soon be described that the paste as it is scraped will beremoved from the under side of the paper or other material beingoperated upon and deposited back into the said paste receptacle.

0 is the paste roller; it is carried byashaft suitably journaled inbearings upon the upper edges of the sides 0' of the table and thisroller is arranged to revolve with its lower portion in the pastereceptacle as seen in Fig. 1; it may be of any desired character and mayor may not be hollow as seen in Fig. 1 as may be desired.

D is a shaft removably supported in suitable bearings in advance of thepaste roller as seen in Figs. 1 and 2 and on this shaft are supportedthe desired number of spools D upon which is designed to be rolled thepaper, cloth or other material to be employed. Only two are shown butothers may be employed according to the character of the work.

D is a cross bar or rod arranged between the shaft D and the pasteroller as shown in Figs. 1 and 2, and this rod or bar is Verticallyadjustable in any suitable manner as for instance by set screws d sothat it may be made to press with more or less force on the paper andkeep it in close contact with the paste roller as seen in Fig. 1.

E is a scraper arranged to be adjusted verticallyin any suitablemaunerand this scraper is located just beyond the paste roller and overthe paste receptacle so that the paste removed from the paper therebywill fall back into the paste receptacle. F are bars or rods, one uponeach side of the scraper and these are rendered adjustable vertically byset screwsfand are for the purpose of guiding the paper upon each sideof the scraper.

G are rods suitably held in the sides 0 and one of them may be a rollerover which the paper passes and after passing over this roller the twostrips are passed, the one under the top rod and the other under thelower rod, as seen in Fig. 1, to bring them in different vertical planesas seen in said Fig. l; and at a suitable point in the sides 0' are heldthe rods or bars G on the same horizontal plane but one in advance ofthe other as shown in Fig. 1, and G are other bars or rods alladjustably held in the sides 0 as shown and whch may be of the numbershown or more or less as may be found most expedient. All of them serveas rollers over which or under which the paper or other materialtravels.

Between the rods G and G are the rods or shafts H upon which are adjustably sleeved the collars h which carry the depending rods or arms hwhich engage the strips of paper and serve to hold them at the regulateddistances apart. The collars on the second shaft H are set nearertogether than are the others so as to cause the two strips of paper toapproach each other as seen in Fig. 2 so that after they pass said pointthe edge of one will overlap the adjacent edge of the other as seen inFig. 2 toward the right. This constitutes what I term the roller systemwhich is subject to slight variations as occasion may require.

I is a stationary cutter suitably secured at the end of the table asseen in Figs. 2 and 4 and J is the movable knife which is pivoted nearone end as at j and has a short arm j extended beyond the pivot as seenin Fig. 4 to which is connected one end of the spring J the other end ofwhich is connected with some fixed part as seen at 7' This knife is tobe operated by hand or foot to sever the strips when desired and isautomatically returned to its normal position, that shown in Fig. 4, bythe spring.

K and K are the strips of paper or cloth or other material and they areshown as being wound upon their spools and the ends led over and underthe paste roller and various rods and rollers and the scraper, andcarried to the end of the machine where they are to be applied to thebox.

The box is designed to be held on the boxholder K which is constructedas seen in Figs. 1 and 2. It may be formed of any suitable material butI prefer thin sheet metal from which the four like pieces K are stampedor otherwise formed. Each part K comprises an arm is at the outer end ofwhich is a rightangled portion 7a which forms one side of the box-holderas seen best in Fig. 2, the right angled portion extending at a rightangle from the arm as seen in Fig. 1. These four pieces are adj ustablyconnected together so as to be adjusted for different sized boxes in thefollowing mannerz-Each arm 7: is passed between two plates L, upon theouter face of one of which is a boss or huh I provided with thumb screwsZ which engage the other plate and serve to draw the two together toclamp the arms 7.: between them; a screw or bolt Z passed through fromthe other plate may sometimes be employed if desired for the attachmentof special box forms. The boss or hub Z carries a shaft M provided withcollars m and set screws m as seen in Fig. 2, and this shaft is designedto be supported rotatably in the shank or bearing n, which is carried byone arm of the cross N as seen best in Fig. 3. This cross is constructedas follows:O is a slotted bar secured in a vertical position at the endof the machine and in the slot of this arm or bar is designed to move aslide 0 on the under side of which is a nut with whichengages a thumbscrew 0 which in turn is passed through a hole in the nut O which isdesigned to slide in the slot of the horizontal slotted arm or bar Passeen in Fig. 3. This horizontal arm or bar carries the hearing 72 abovereferred to. It will be readily seen that by this adjustment thebox-holder may be adjusted to any desired position vertically orhorizontally or both; tightening of the thumb screw holds the parts intheir ad justed positions. By the use of this cross all positions forthe use of different attachments can be readily obtained.

The parts constructed and arranged as above described constitute what Iat present consider as the preferable way of carrying out my invention.

The operation will be readily understood. The strips of paper or clothare fed from the spools over the paste roller and thence over thescraper and the various rollers and by the depending arms or rods hcaused to approach each other and to overlap and become compressed intoone composite strip before they reach the box which is designed to becarried by the box-holder. Here it is attended to by the attendant inthe usual manner.

Some of the advantages attending my construction and arrangement ofparts may be briefly stated as follows: The shears or cutting apparatusbeing stationary is stronger and more steady and insures a truer cut andless tiring than shifting or suspended shears. The roller system isimportant for the reason that it keeps the several strips apart beforethe composition or bringing together is accomplished; the glue under theupper strip is not scraped by the edge of the lower strip when pushedover each other and thus glue soiled edges are prevented. The stripsreach the box after they have been pressed together by the rollers; adiiferent tension can be given when more than one strip is on themachine, according to the width, strength and nature of the paper orcloth. The paper is under the complete control of the operator and thereis no curling, swaying and flopping of the paper or cloth. The guidersact not only to guide the paper but also form a rest therefor. The guideformed by the bars and rollers G transfers the strip entirely under thecovering paper without interference of the edges of the same.

The advantages of the paste apparatus, the cross and the box-holdershave already been set forth in part.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages. The stripguide at the left hand side of the rod nearest to the roller G andattached to the collar It has the shape of the letter U in lyingposition. The upper part of this guide is on a horizontal level with therod to which the collar h is attached while the lower part is suspendedbelow the same. This guide transfers the staying strip for the settingin the bottoms to boxes entirely under the covering paper or strips,without interference of the edges of the same.

YVhat I claim as new is- 1. In an organized machine for the purposedescribed, a paste supplying device, consisting of a tank having aflange upon its bottom and a damper, a paste receptacle removablysupported within the tank and provided at its respective ends with ashield and a hinged flanged cap, suitable guide rollers for the stripsof paper, a severing mechanism therefor, and a box holding device,substantially as and for the purpose set forth.

2. The combination with the tank having surrounding flange below itsbottom, a hinged flanged cap and a damper, of a paste receptacle havingside flanges and carrying a shield at one end, substantially as and forthe purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
